Title: Improvements in combined clutches and brakes
Inventor: TAYLOR LEONARD
IPC: F16D67/04
Filed: 1968-04-18
Abstract: 1,262,640. Clutches; clutch/brake combinations; disc brakes; cooling. L. TAYLOR. 17 April, 1969 [18 April, 1968], No. 18375/68. Headings F2C, F2E and F2L. Cooling of a clutch/brake combination for a power press, is effected by scoops 50A rotating with the clutch or brake and directing air through passages 51, 52 to the friction elements of the clutch and/or brake. As shown, three scoops 50A rotate with a brake hub 40 fast with a driven clutch hub 17 splined on the press crank-shaft 16. The hub 17 is driven through friction plates 23A from a driving clutch member 23 bolted to a V-belt-driven flywheel 20. The clutch is engaged by an annular compressed-air-actuated piston 34 mounted in a cylinder 33 on the brake hub 40. Springs 42 withdraw the piston to release the clutch and apply the brake. The piston and hub 40 carry brake linings 41 which engage either side of a fixed annular disc 14 to apply the brake. The passages 51 extend axially through the hubs 40, 17 and passages 52 extend radially between the plates 23A and through the piston 34, linings 41, and disc 14. The disc carries cooling fins 14A, and may additionally be water-cooled, Fig. 6 (not shown). A self contained motorized fan unit 60 directs cooling air through a nozzle 61 on to the brake. Two or more brake discs may be provided.

Title: Improvements in or relating to forming bulges or corrugations in metal tubes
IPC: B21D17/02
Filed: 1944-02-23
Abstract: 570,093. Corrugating POVEY, W. A. Feb. 23, 1944, No. 18503. [Class 83 (iv)] In the formation of a bulge or corrugation near the end of a tube, jaws each formed as a part die grip the tube, internally supported by a mandrel, whilst a punch surrounding the mandrel and formed with a recess complementary to that formed in the jaws, is advanced to apply end pressure to the tube. The jaw 1 is guided on pins 34 secured in the jaw 2 and having heads 35 sliding in counterbores 36. A spring 38 tends to separate the jaws. The jaws are closed on the tube 5 by means of a vice the projection of the tube being regulated by a stop 33 pivoted on a rod 32 mounted in a boss 31 in a block 17 connected by pivoted links 13, 14 to the jaws. A hollow spindle 19 screws through the block 17 and has a collar 20, carrying the remainder of the die recess, mounted in a counterbore against a thrust bearing and retained by a screw cap 22. The spindle 19 is operated by a hand lever 29. The mandrel 26 passes through the spindle 19 and projects to an extent controlled by screw engagement at 27. In a modification the stop 33 is held by a spring against the mandrel and has a tail engaging the link 13 so that as'the vice closes the jaws on the tube the stop is swung aside. According to the Provisional Specification the spindle 19 may carry a lock nut to limit the feed, and the tool may be operated hydraulically or pneumatically.

Abstract: 667,406. Magnetic chucks. BOHLI, J. July 14, 1949 [July 23, 1948], No. 18606/49. Class 60. A pole-plate for a magnetic work-holding device comprises pole-bars 12 which are arranged side by side, are completely separated from one another by gaps 13, and have laterally extending wings 2a, 4a, 6a which intermesh with one another in the work-holding area of the plate, each pole-bar presenting a smaller area to the work than to the magnet. The pole bars may be made from laminations 2, 3, 4, 5, 6 assembled in the order shown and riveted together between side bars 1, the clearances between the pole bars being filled with non-magnetic metal or synthetic resin. The material below the broken lines 14 is milled off after assembly so that each pole bar is provided with a broad rectangular base to engage the poles of a magnet plate which may be of either the permanent or the electromagnetic type. To render the pole plate non-magnetic it is moved by half the pitch of the pole bars relative to the magnet plate. The pole bars may alternatively be made by milling whole steel bars or by casting. The wing thickness is between the limits of 0.5 and 1.5 mm. and the arrangement and relative area of the wings may be varied to suit different kinds of workpiece.

Filed: 1960-05-27
Abstract: 923,732. Bearings. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. May 26, 1961 [May 27, 1960], No. 18926/60. Class 12 (1). [Also in Group XXVIII] In a gas compressor a piston which compresses gas into a reservoir, is reciprocated in an hydrostatic gas bearing supplied by gas from said reservoir. In an embodiment the piston 2, having polepieces 13 thereon, is actuated in a cylinder 1 by a reciprocating rod 15, having magnets 14 thereon. Gas, supplied at 11, is compressed in a chamber 1a and is passed to the reservoir 5 via a port 3, a valve 6 and a pipe 4. The pressurized gas is supplied from the reservoir through pipes 5a, 10 and the latter connects to a manifold 7 which is formed between a sleeve 9 and the cylinder 1. The gas then passes through ports 9a in the sleeve 9 and into the clearance space between the sleeve 9 and the piston 2. The gas returns from said clearance space to the chamber 1a via annularly-spaced channels 12. In modifications, the piston may have capillary bores which convey gas to the bearing; the clearance between piston and cylinder may be controlled by cooling the cylinder wall or by heating the piston, in the latter case the piston would be hollow to receive a heating element 16; and the piston may be actuated by a solenoid, the piston being of magnetic material.

Abstract: 241,501. Oxe, H., and Oxe, W. July 25, 1925. Lock mechanism, operated by non-rotating key; padlocks; keys.-In a lock of the kind wherein spring detents in a casing engaging shoulders on an inserted bolt and are released by insertion of a flat key, the detents are of unequal length and the bolt shoulders and key-bit stepped to correspond. The casing a, b has the plate c from which tongues i of unequal lengths are stamped, attached to it below a ward plate c<2> which necessitates a corrugated key. The bolt k has stepped shoulder k<4> in recesses g and is recessed to correspond to the ward plate. When the bolt is inserted into the casing until it is stopped by the pin e, the tongues i snap behind the shoulders k<4> preventing release until the stepped bit l of the key is inserted to depress the tongues. The shoulders k<4> form the stops to limit the insertion of the key. The key can fold into the handle l<1>. The casing and bolt may be attached to the ends of a chain.

Filed: 1949-07-20
Abstract: 659,258. Pivoted sliding windows. ARNOLD, J. C. (Robertson Co., H. H.). July 20, 1949, No. 19125. [Class 20(iii)] A window structure in which a window pivots as well as slides comprises a sash frame 22 with pivot pins 26 extending into a pair of vertical rails 24 sliding with the sash in grooves in the window frame 10. The marginal edges of the sash frame and the adjacent edges of the slide rails have grooves 32, 28 facing each other, and vertical locking bars 34 in the sash grooves 32 have inclined slots 58 engaged by pins 50 fixed in the side walls 52, 54 of the sash frame, so that the bars 34 move diagonally in and out of engagement with the slide rail grooves 28. The bars 34 are urged into locking position in the grooves 28 by a compression or other spring 60 bearing on the top of the bars 34. Thus when the bars 34 are lifted diagonally against the springs 60 by digital pressure at their lower ends 66 out of engagement with the grooves 28 in the slide rails 24, the window may be pivoted about the central pins 26. The locking bars 34 are operated to allow pivoting only when the sash has been moved from closed position. The structure may comprise two windows sliding in parallel grooves in the frame. When the sash frame is pivoted, the springs 60 press the bars 34 against the slide rails 24. A metal weather strip 46 between the slide rails 24 and the window frame channels reduces rattling. The window structure may be wholly of metal, the glass 82 being held by a spring metal member 86 wedged between a liner 84 on the glass and an extension 88 of the sash frame.
